there is no such thing as SATA-II or SATA-III
SATA150 / SATA300 exist.

SATA2 or SATA3 are incorrectly used and are not official.

Quote:

The SATA-IO, or SATA International Organization, specifies that the SATA standard has the potential to top 6Gbps transfer rates; four times what the majority of drives currently offer. While it is probably questionable if 3Gbps transfer rates are even obtainable outside all but the most intensive SATA RAID scenarios, the fact remains that "SATA II" - the name - has absolutely nothing to do with data rates.

should be SATA300 system and I agree partly; yes with a newer system the Vertex SSD will perform better, but even in a system where the bottleneck is SATA 150 controller, you will notice a difference; maximum transfer is nice, but low latency and extremely high multi I/O performance of these SSD give the biggest boosts; to older systems will always benefit from a storage medium upgrade

Sadly, there is little point in paying for that kind of speed because you're not going to get all of it unless you're using a SATA-II system.

That's an unfortunately under researched and documented point: SATA I is out there in millions of laptops and desktops. While one can drool over all the "Peak" Sequential Read data specs of the latest SSD models, at what point does REAL-WORLD use start to truly max out a SATA I controller???

I've yet to encounter any of the deep-geek reviews talking about the issue of precisely when SATA I controllers become a bottle-neck -- Or exactly which drives are best suited for SATA I limitations.

I bought an OCZ SOLID series value drive for my old Intel MacBook - dirt cheap. Should I have paid up for a Apex or a Vertex? Would it have been 'worth' it???
